Abstract:	The vegetal products harvested at spring time from the birch tree, known as spring elixirs, are the birch sap (Betulae limfa or succus) and the birch tree foliar buds (Betulae gemmae). This study was concerned in gathering information regarding the harvest process of the birch sap, organoleptic description of both the sap and foliar buds, as well as regarding diuretic and uricosuric activity (in vivo, on animal model) and the antiproliferative effect (phytobiologic test on Lepidium sativum grains). Diuretic and uricosuric activity of the birch sap is superior compared to the bud extracts and the antiproliferative activity evaluated through the inhibition of germination of Lepidium sativum grains, which can indicate a possible antitumoral activity of several dilutions of the birch sap and aqueous extract from birch foliar buds.
